Lost the red color from my Sharp LCD TV

Check the ventilation fins on the back. Sometimes they get obstructed with dust and then heat builds up. The TV then shuts down to protect itself from overheating. You can use a blow dryer to blow it out.

Examine the set with the color OFF and if No blue (odd problem) check hookup----component uses red, green and blue cables and if blue cable is bad and signal is from component on a box---box could be bad.

Easy way to know---hook DVD etc to a rear inputs= still no blue?

try going into the menu and resetting the color .

one of the video boards. Great TV! worth getting repaired.

In the steup menu there should be a setting called "HUE" try adjusting that. If that does not work, you may have lost "green drive" circuits in your TV.
If the menu windows have the right colors, try playing a DVD or a video on it. If they look good you may have a problem with channel tuner or antenna.

Try a different AC cord first the one you have may a resistance problem. Also try plugging it into a different wall outlet. If still the same problem, somehow your convergence circuit has a fault.

But see if another ac cord works for you first...

get back to me on this when you have time.....

That TV needs a 4 code remote.
Mine uses code 1702 on a Phillips SRU2103/27 I got from Sears for under $10.
